Overview

Social-awareness has recently attracted a high level of attention in network management. The CNSM Workshop on Social-aware Economic Traffic Management for Overlay and Cloud Applications (SETM 2013) is the continuation and evolvement of three successful Economic Traffic Management workshops, where the last workshop was co-located with ITC22. The workshop title has been changed to better reflect the scope of the workshop that basing on economic perspectives in network management extends its scope towards social awareness, cloud computing, content awareness, and CDNs. That way the workshop is following current trends in that area.

The main objective of the CNSM Workshop on Social-aware Economic Traffic Management for Overlay and Cloud Applications "SETM" (supported by the EU FP7 projects SmartenIT and eCOUSIN, as well as the DFG Cooperative Research Center 1053 MAKI) is to give scientists, researchers, and operators the opportunity to present innovative research on SETM, to discuss new related ideas and directions, as well as to strengthen cooperation in this field of economics-technology interplay. The SETM 2013 workshop is financially sponsored by Orange and Intracom Telecom.

Scope

In the current Internet, important new overlay and cloud applications significantly influence volume and patterns of Internet traffic. While overlay applications such as Content Delivery and P2P store and circulate information among each other with no awareness of the topology and state of the underlying transport network infrastructure, cloud applications delegate storage and computation to the network, which is valuable for devices with limited resources and access.

At the same time, Online social networks (OSN) like Facebook gain more and more popularity and attract millions of users. The widespread adoption of OSNs has drastically changed the way content is consumed in the Internet, as content consumption is nowadays highly impacted by the information shared by users through OSNs and the popularity of a given content is most often dictated by its "social" success.

In turn, the adoption of socially-aware traffic management mechanisms as a new management approach allows for a tighter integration of network management and overlay service functionality which can lead to cross-layer optimization of operations and management, thus, being a promising approach to offer a large business potential in operational perspectives for all players involved. This approach shows benefits for overlay and cloud applications and services which are currently dominating Internet traffic, but still have a large potential for optimization, e.g. in terms of QoE, energy efficiency, inter-cloud traffic.
